Appliccticin filed January 18, 1905. Serial No. 2 .4571- T0 at 10771017, may concern:

1 Be it known that 1, ROBERT Lnn Rrormnm SON, a citizen of the United States, and a resident of Keota, in the county of Keokulr and State of Iowa, have invented new and useful Improvements in Extension and other Tables, of which the following is a. full, clear, and exact descri tion.

The nature 0 my invention consists, cssentially, in the employment of a lurnlity of side sections for the top-frame 0 an extension-table or for a nonextension table, said sections bein formed of plate metal and each provide with a longitudinally-extending tribulation which is open at one side, but exceeds a half-circle in cross-section, whereby said frame-sections are adapted for telescopic connection in sequence and when so engaged are prevented from lateral disengagement.

The invention furthermore comprises a.

7 novel construction for the corner portions of the top lrame of the table, other features of improvement being shown, which will be. hereinafter fully described.

The invention consists in the novel construction and combination of parts, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming at part of this specification, in which similar characters of reference indicate corresponi'ling parts in all the figures.

Figure 1 is a perspective view of an extension-table embodying features of the invention. Fig. 2 plan view of the same partly broken away. I Fig. 3 is a longitudinal sectional view substantially on the line 3 in Fig. 2. Fig. '3 is an enlarged longitudinah sectional view of an end portion of e tableleaf, showing a detail of the invention. Fig. 4 is an enlarged perspective view showing one corner of a table-top frame oi novel construction.

Fig. 5 is a. broken perspective view of a corner-bracket that is a detail oi" the invention. Fig. 6 is it perspective view of one of a. plurality of lop-frame sections employed. Fig. 7 is a transverse sectional view of a. locking-plate that is a portion of each corncrbracket employed, the section being taken substantially on the line 7 7 in Fig. l. Fig. is a transverse sectional view of the some substantially on the line S 8 in Fig. at; and Fig. 9

is a perspective view of portionsof two topfrnme sections for the improved table, showing their telescopic engagement and means carried by said heme-sections that limit their sliding movement one within the other.

The table-top frame is rectangular and comprises it suitable number of sections for each side and end thereof, to be determined by the dimensions given to the completed table. blanks cut from plate metal, steel plate of proper gage being preferably employed, which Each frame-section 10. is formed wit an integral tubuletion 10, extending throughout its length, preferably at the center of width, and, as shown, said tubulation on each framescction is projected from the exterior side thereof. The tubulntion 10 of each framesection 10 is of a suitable diameter to ailord necessary rigidity to the section, the diameters of the plurality of sections forming the sides of the top-frame being so proportionedthat they have close-fitting telescopic engagement one with the other in sequence. It is essential for the proper sliding engagement of one tribulation 1O with the next one in sequence that said tribulations be more then a. semicircle in their curved wall, transversely considered, so that when introduced endwise one into the other the smaller one cannot be displaced through the gap a left between the fiat portions of the frame-section and that occupy the same vertical plane when the parts of the table are assembled for service.

To further stiffen the top-frsmeseotions the frame should have a flange 1O turned inwardly at a. right angle from the fiat portion thereof that extends above the tubulation 10, said flanges being disposed practically in a horizontal plane when the table- 'lra'me is setup for use. It is to be under:

top frame are to be formed of late metal and tubuleted in c. manner simi or to the side frame-sections 10, these end portions 10 being each made up of one or more sections, as may be prcierred, (see Figs. 3 end 8,) and each provided with it top flange corresponding with the llcnges 10 on the side sections 10.

Four similar corner-brackets are provided eflords requisite strength and li htness:

The frcme-sections 10 are formed of 10, each of them adjacent to the corners of stood that the like end portions of the tzrble- IOO es cem cl fneetery cf th frame, Ellitl, shown, each consist A erably structure he rin grel side cclticrzs that are (lispesec ct esaglc c e the ether The si e Wells 1i cf each ccrn-er-hreclaet eye formed with letions 11*; similar t0 the tubule-liens 10 and it "will be noted. Figs. :3 and 4 met tabulations cnthe side and end sections cf the table-top heme fit neatly buletions 11 inte which they are inserted endwise. are secured upon the corner-brackets by screws or z'ivets, as is incliceted in Fig at 3;, end es the cast comers of the hip-"Heme may he Quite thiil and given any desired style of ornamentation On their cuter siulsces they add to the ornate appearance of the table.

The side sections 10 of the top-frame are each provided with en clmtment-toc 0, formed on the lcwer edge of :1, depending flange thereof, and these abutnients on the adjacent ends of said frame-sections are so termed and ermnged that en abutment on one depending flange will he adapted to im pinge upon the abutment on the fmmesecticn 10 in which it slides, which contact will prevent the inner frame-section from leaving the enter one when the fi'mne-scctlons ei'e "fully extended, this relative arrangement cl parts being shown in Figs. 3 and 9,

Four legs 12 oi any ornamental design are gzrovided for the support of the table at its cancers and me lietcchchly connected them with, the novel means for acting such s ccr necticn as shown consistmg of the following details? On the engulcrly-connected sides of (Ruth corner-bracket l1 and flush with their lcWcx' edges 11 bese-plcte 11 is integclly formed and extends across the bracket in s, normally horizcfitel lene, Sfllfl ilet base-plate having a keyhole-slot d formed in it opposite the cmner of the bracket and near the center 0?" the plate, as indicated in Figs, 5 and 8. Beneath the flanges 10-" on the to -frsme secticns 10, that secured to each corner-bracket, e locking-plate i1 is secured thereto, each locking-plate being a (l plicete of the base-- late 11', above which it is directly located. I each locking-plate 11w keyhole-slot e is formed, which located in a recess 6, formed in the upper side of said locking-plate; and, indicated in Figs. 4, 7, and 8, the depression in the 11' er side of each lockin -slate is in clined somewhat on the bottom, being lowest at the narrow end of the key hole-slc t e eppc site and comparatively near the corner of e respective bracket Where the side walls 11 join, and it will be noted in Fig. 8 that the slots d and e are disposed one directly above the other.

In the fiat upper end of each leg 12 is secured the lower end of e locking-holt 13 and preferably is projected axially therefrom The side end end Temesectioz s cachet these similcr- 12- hc'iing c heed oi the same. Lhe lleec 01 each lockingbolt 13 is projected leterellyttic i i he ecit end is cf such as ,l as s it yo te fit lcosely in the keyholeslots e, through which is is to be passed upward 11 th (1' at e 15 tence between the lower side cl each bolt encl the flat top fece of e pest 12, frcm itprcjects, is such that W en the beltlvody is passed up through the sliced slots d and e the head g, wilich mey be turned around bye rotatable movement of the post, will ride upoe the inclined bottom surface of the recess c end by its cam-like action drew the into close contact with the lower surface of the base-plate 11, thus firmly securing the leg in piece on the corner-bracket. It Wlll be seen that if the legs we of equal length and the base plates 13 are disposed 3 in the seme'plene when the comer-brackets and side sections of tecle ssemblezl the table as en'entiret F surfs-(3c of its frame su Jetted evel are seated men a supper hormente; so

A suitelne number of tsble-lesves furnished i,ilf0l'll1 the tchleto a? placed tlansvei'sely en tithe top-frame sections 10, ets and the end frmnc mg c continucus level tel formed of eeysuitelile finished.

The

2: k v A -n An slgnec cc new its top homes idlluwiS-c; seer 30 tionary, then all of the latter may be secured upon the respective top flanges 10 and the table rendered squa e or of any desired length, depending ufpon the length of the end portions 0 the toprame.

It will be seen that by constructing the entire upper portion of the table, exce t the leaves 14, of sheet metal and very ligiit cast metal an'exceedingly light but strong table is afforded that may be changed for length quickly, and as the tubulations 10 on the side-frame sections, as Well as on the corner-brackets, are, in effect, slotted tubes, one

fitting neatly but slidably in a matin one,

the table-top frame at any oint of siding adjustment is strong and rigld, resisting torsional strain, as well as pressure, on its upper side to a remarkable degree.

Asthe abutments c on the lower edges of the plate-metal side frame-sections 10 may be caused to pass each other by s ringing the frame members laterally, it will be seen that the, top-frame members may be separated from each other, and they may also be disconnected from the bracketframe members 11, if their connecting means is in the form of screws, so that a table in finished condition may be knocked down and all parts packed into a very compact package for transportation, and said parts may be again assembled for use as a table very expeditiously and in a perfect manner with but the use of a screw-driver.

Owing to the material used and the peculiar novel construction of the table, the use of a center leg is dispensed with and the wei ht of a table of iven dimensions is very muc less than a tab e of like size formed of wood in the usual style.

a n is obvious that the table may be'finished throughout in any preferred manner and be rendered a highly-ornamental piece of furniture.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A table-top frame, comprising a plurality of plate-metal sections, each having a laterally-projected cylindrical tubulation that has a slot-like opening therein, said tubulations slidably engaging one within the other through said openings, whereby they are held from lateral displacement.

2. A table-top frame, comprising a pl urality ofplate-metal side sections, each provided with an integral outwardly-projected cylindrical tribulation longitudinally thereon, each tubulation having a narrow gap or slot-hke opening extended throughout its length, the diameters of said tubulations being varied so as to ada )t one tribulation to slide in the adjacent tribulation that is of greater diameter, the inner tubulation having a neck where it joins the flat portions of the side section it is on, said neck Working in the gap or slot and thus adapting one tubulation to slide in a corres onding one.

3. l a table of the character described, the plurality of removable wooden tableleaves, each having a rectangular transverse groove near each end and in the lower side, and a thin metal shoe embedded in each groove, said channeled shoes receiving the upper edges of the top-frame sections when said sections are extended,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
